12 * @brief (Cross-process, MCer/MCed) Access to SMX structures
14 * We copy some C data structure from the MCed process in the MCer process.
15 * This is implemented by:
17 * - `model_checker->process.smx_process_infos`
18 * (copy of `simix_global->process_list`);
20 * - `model_checker->process.smx_old_process_infos`
21 * (copy of `simix_global->process_to_destroy`);
23 * - `model_checker->hostnames`.
25 * The process lists are currently refreshed each time MCed code is executed.
26 * We don't try to give a persistent MCer address for a given MCed process.
27 * For this reason, a MCer simgrid::mc::Process* is currently not reusable after
33 /** Get the issuer of a simcall (`req->issuer`)
35 * In split-process mode, it does the black magic necessary to get an address
36 * of a (shallow) copy of the data structure the issuer SIMIX process in the local
39 * @param process the MCed process
40 * @param req the simcall (copied in the local process)
